Planar laser-induced fluorescence (PLIF) of hydroxyl (OH) and formaldehyde (CH2O) radicals was performed alongside stereo particle image velocimetry (PIV) at a 20 kHz repetition rate in highly turbulent Bunsen flame. A dual-pulse burst-mode laser generated envelopes 532 nm pulse pairs for PIV as well pair 355 pulses, the first which used CH2O PLIF. diode-pumped solid-state Nd:YAG/dye system produced excitation beam OH The combined diagnostics simultaneous, temporally resolved two-dimensional...
The goal of this research is to empirically identify the boundaries between different regimes premixed turbulent combustion that appear on diagrams Borghi and Williams.To date, four conditions have been extensively studied.The most intense possesses a turbulence level (u'/S L ) 185, an integral length scale (λ/δ F,L 46, Reynolds number 69,000.At present, data set too limited plot regime diagrams.However, categorized into their appropriate regimes.The structure thicknesses reaction zones were...
Abstract Swirl-stabilized, turbulent, non-premixed ethylene–air flames at atmospheric pressure with downstream radially-injected dilution air were investigated from the perspective of soot emissions. The velocity and location jets systematically varied while global equivalence ratio was kept constant 0.3. employed laser diagnostics included 5 kHz planar laser-induced fluorescence (PLIF) OH, 10 Hz PAH-PLIF, incandescence (LII) imaging particles. OH-PLIF images showed that reaction zone widens...
Structural features of highly turbulent piloted flames were acquired from simultaneous PLIF images formaldehyde (CH 2 O) and OH.The lean (equivalence ratio = 0.75) methane-air studied under eight different flow conditions at two interrogation regions.The non-reacting for these consist Reynolds numbers (Re T ), turbulence intensities (u'/S L integral length scales that range 520 to 80,000, 5 184, 6 mm 29 mm, respectively.Preheat reaction zone thicknesses measured subjected values.The preheat...
Structural features of highly turbulent piloted flames were acquired from simultaneous PLIF images formaldehyde (CH2O) and OH.Both lean near-stoichiometric (equivalence ratio ϕ = 0.75 1.05, respectively) methane-air studied under twelve different flow conditions at two interrogation regions.The non-reacting for these consist Reynolds numbers (ReT), turbulence intensities (u'/SL), integral length scales that range 520 to 80,000; 5 185; 6 mm 37 mm, respectively.Eight the cases have u'/SL > 25...
Swirl-stabilized turbulent spray flames operating at atmospheric pressure, with both a conventional Jet-A kerosene (‘A2’) and synthetic fuel blend (‘C5’) radially-injected dilution air were investigated from the perspective of soot emissions in model Rich-Quench-Lean (RQL) combustor. The primary downstream flow split was varied while keeping global equivalence ratio constant (ϕg=0.4). 2.5 kHz PIV, 5 OH-PLIF, simultaneous 10 Hz Mie scattering LII used. Results revealed correlation between OH...
Lean blow-off (LBO) conditions, duration of the extinction transient, and flame structure were investigated for swirl-stabilised, fully-premixed flames operated with methane vapourised kerosene. High-speed (5 kHz) OH* chemiluminescence, OH-, Fuel-PLIF imaging used. Low-speed (10Hz) CH2O-PLIF was also implemented to visualize CH2O. chemiluminescence LBO transient suggested that primary reaction regions confined within central recirculation zone (CRZ). Sharp temporal increases in signal...
Abstract The resonance of diurnal tidal elevations is investigated with a forward ocean tide model run in realistic near-global domain and synthesis free oscillations (normal modes) computed for global geometries physics. As prelude to performing the simulations, topographic wave drag, which now commonly employed models, tuned specifically tides. predicts reasonably well sensitivity changes frequency, zonal structure, meridional structure astronomical forcing. Three that are important...
